Simon Brunel 50a80da1e9 Fix and refactor bar controllers
Merge most of the horizontalBar controller into the bar one but also fix stack groups and bar positioning when scales are stacked or when a min and/or max tick values are explicitly defined. Note that this is a breaking change for derived controllers that rely on the following removed methods: `calculateBarBase`, `calculateBarX`, `calculateBarY`, `calculateBarWidth` and `calculateBarHeight`.
